Here's a riddle for you.
There are two streets in Montreal that share the same name (almost, one adds the word "du"), are about 12km from each other and both lie entirely north of Gouin Blvd. (though still on the island).
Their common name evokes forestry, though isn't the name of any individual type of tree.
What are their names?
UPDATE: Five of you got this one right: Rue Bocage in Ahuntsic and Rue Du Bocage in Pierrefonds. Though extra points for those who noticed that there are two Rues Du Pont, in Ste. Geneviève and Ahuntsic. (The first, notably, doesn't actually lead to a bridge.)
